How to Buy a Used Computer.
Instructions
Step 1:
Assess the price of a used computer. Used computers shouldn't cost more than a brand new computer, but that depends on what specifications the used computer has. Used computers with a lot of software and hardware (such as CD drives, DVD drives and larger hard drives) will generally cost more.
Step 2:
Decide on the type of computer you want. Ask questions about use. Computers come with a variety of different specifications. Some are necessary for Internet use. Most computers come with standard hardware and software such as an operating system, CD or DVD drive and Internet capabilities. But not all systems are created equal, especially used computers.
Step 3:
Investigate the quality of some used computers. Always ask questions about the computer's past use. Inquire if it ever had a virus infection. Find out if it ever had other repair work. Ask the same sort of questions that would be asked when buying a used car.
Step 4:
Determine what usage the computer will get. Younger kids may not need the computer for anything other than educational games and word processing, but older kids may need it for school and research. The use the computer gets determines how fast and modern the used computer needs to be.
Step 5:
Find a place to buy a used computer. Computer shows are a great place to find a used computer. Flea markets are also another possibility. Some computer shops have access to used computers or computers that have been used as display models. Check out garage sales or read the newspaper's classified section to find used computers.
The new Radeon HD 4770 is the world’s first 40nm graphics processing unit, and although it's not designed to set any speed records like the flagship 4890, the 4770 aims to deliver the best possible value in a neat cost-effective package.
Intel Core i7 920, 940 and 965 Extreme Edition
The Core i7 965 Extreme Edition runs at 3.20GHz and features a QPI (QuickPath Interface) throughput of 6.4GT/s, which is the key difference here. The mainstream versions of the processor include the Core i7 920 and 940, clocked at 2.66GHz and 2.93GHz, respectively. These more affordable processors feature a QPI throughput of just 4.8GT/s, so it will be interesting to discover what kind of impact this has on performance.
AMD Phenom II X4 955 Black Edition review
The new Phenom II X4 looks as having the potential to be the ultimate upgrade solution for AMD users, giving Core 2 Quads a good run in every possible way.
Cooler Master HAF 922 Mid Tower ATX case review.
The HAF 922 builds on the success of the original full ATX case, supporting up to 7 large low-RPM fans, tool-less expansion bays and slots, and smart design meant to optimize air flow.
Hitachi Deskstar 7K1000 (1 Terabyte) Hard Drive.
The Deskstar 7K1000 represents a milestone for Hitachi and for the hard drive industry as a whole, as it is the first drive to offer a 1 terabyte capacity. Honestly, I expected that it would be Seagate who would deliver the first 1TB hard drive since they were the first to reach the 500GB mark
